Cutoff For selection in cs??
It would be good if you could tell which particular exam you are talking about because the cut off varies exam and college wise. Also, as per my assumption your query should be regarding Jee Main (please correct me if I am wrong) so for top NITs your score range should be 230-270 for CSE so plan and prepare accordingly and to check previous year cut off trend you can go through the below link -
